  • the electrical power originating from both the generator and the fuel cell form the output of the installation.
  • Difficulties associated with the Hendricks system are complexity and it has a high capital cost, in that it requires multiple turbines. Accordingly, there is a need for small scale power installation units that have high energy efficiency, have capital and operating costs comparable to those of large scale installations, and create minimum pollution.
  • the present invention is directed to a system for generating electricity that satisfies these needs.
  • the system comprises as its main components (i) a fuel cell, (ii) a heat exchanger, also referred to as a heating stage or recuperator, and (iii) an integral power generator.
  • the integral power generator comprises three units on a single shaft, namely a compressor, an electricity generator, and a turbine.
  • This system operates on fossil fuel, preferably natural gas, and inexpensively and cleanly generates electricity.
  • oxygen-containing gas typically air
  • Fuel and the compressed gas, serving as an oxygen source, are introduced into the fuel cell through an inlet, wherein the fuel is converted by oxidation to produce electricity, water, and hot a exhaust gas.
  • the electricity produced by the fuel cell is one source of electricity generated by this system.
  • Additional electricity is produced by the turbine generator. This electricity is obtained by taking the fuel cell exhaust gas and introducing it into an inlet of the turbine as a drive gas for driving the turbine, which in turn, because they are on the same shaft, drives the generator and the compressor.
  • the turbine operates at at least 50,000 RPM, and generally from about 70,000 to about 90,000 RPM.
  • the generator produces a high-frequency alternating current, typically at least 800 Hz, and generally from about 1 ,200 to about 1 ,600 Hz.
  • the power from the generator can be converted to direct current, and then combined with the direct current electricity from the fuel cell.
  • This combined direct current can then be inverted in an inverter to produce relatively low-frequency alternating current for consumption, typically having a frequency of 50 to 60 Hz.
  • Spent turbine drive gas once discharged from the turbine through an outlet, is used for heating the oxygen-containing gas fed to the fuel ceil in the heating stage by introducing spent turbine drive gas into an inlet of the heating stage.
  • the exhaust gas from the fuel cell may be at a higher temperature, i.e, about 1 800°F, than commercially available turbine power generators can operate, which is generally in the order of only about 1 600-1700 °F. Therefore, preferably, the turbine drive gas includes a sufficient quantity of compressed gas from the compressor to maintain the turbine drive gas at a sufficiently low temperature that it does not damage the turbine.
  • water be combined with the compressed air before it is introduced into the heat exchanger to maximize the heat recovery from the turbine exhaust gas.
  • the water used for this purpose can be water generated in the fuel ceil or from an independent source.
  • a power generator 10 comprising a compressor 12, an electrical generator 14, and a turbine 16, all sharing a common shaft 17;

  • the turbine 16 can be between the generator 14 and the compressor 12, or the compressor 12 can be between the generator 14 and the turbine 16.
  • a suitable power generator can be obtained from Capstone Turbine Corporation of Tarzana, California.
  • the Capstone power generator referred to has a turbine 16 which generates about 24 kW.
  • Another satisfactory power generation will be available from Allied Signal of Torrance, California, which has a turbine providing from about 40 to about 50 kW, and larger units are planned up to 200 kW.
  • the compressor 12 and the turbine 16, which turn on a common shaft with the generator 14 at high speed, can each or both be radial (centrifugal) design, or both can be an axial flow design.
  • the bearings required for the power generation unit 10 can be located on the shaft 17 with the generator 14 cantilevered on the shaft, or the generator 14 can be located between the bearings. Air bearings are preferred to reduce the complexity of the machine.
  • the high speed generator 14 uses a permanent magnet to supply the necessary magnetic lines of force.
  • the fuel cell 18 catalytically converts methane to hydrogen and carbon dioxide with heat generation; and the hydrogen is then combined with oxygen in an oxygen-containing gas to generate electricity, plus waste heat and water.
  • fuel cells are suitable for use in the system of the invention.
  • One type that can be used is a molten carbonate fuel cell.
  • a phosphoric acid fuel cell can be used.
  • a low-temperature fuel cell, such as a proton exchange membrane or phosphoric acid can be used, but with less efficiency.
  • the preferred fuel cell is a solid oxide fuel cell, which typically operates at a temperature from 1 600 to 1 800°F.
  • a solid oxide fuel cell can be obtained from Westinghouse, Pittsburgh, Pennsylvania.
  • the Westinghouse fuel cells can be obtained in any size, in 250 watt increments.
  • the heating stage 20 can be a fixed recuperator or a revolving regenerator.
  • the rectifier 22 is typically a diode system whose purpose is to convert high-frequency alternating current to direct current.
  • the purpose of the inverter 24 is to convert direct current to a low- frequency, alternating current, typically 50 to 60 Hz, for domestic use.
  • Table I provides the temperature, pressure, and flow rates of the various streams of the system shown in the drawing.
  • the inputs to the system are an oxygen-containing gas, typically air 32, and a fuel 34, which is typically natural gas, which is principally made up of methane.
  • the input air 32 is used for oxidizing the fuel 34 in the fuel cell, after it is compressed and heated.
  • the air 32 is first compressed in the compressor 12.
  • the compressed oxygen- containing gas 34 is then heated in the heating stage 26, to produce the heated, compressed, input oxygen-containing gas stream 37 for the fuel cell 18.
  • the oxygen-containing gas is typically air 32, it can be other gases containing oxygen, such as air partially depleted of oxygen, or air enriched with oxygen.
  • the outputs from the fuel cell 18 are direct current electricity 38, water 39, and hot exhaust gas 40.
  • the temperature of the exhaust gas 40 depends upon the temperature at which the fuel cell operates. For efficiency, preferably the fuel cell 18 is operated at as high a temperature as possible, subject to the material limitations of the fuel cell. For the preferred fuel cell 18, this is in the order of about 1800°F.
  • the fuel cell by itself typically
  • the purpose of the power generation unit 10 is to take advantage of the energy content of the hot exhaust gas 40 from the fuel cell.
  • the efficiency of a commercially available power generation unit by itself, is typically about 30 percent.
  • spent fuel cell exhaust gas 40 is used as a turbine drive gas 48 for driving the turbine 16. Because the generator 14 and compressor 12 are on the same shaft as the turbine, the generator 14 turns, producing alternating current electricity 50, and the compressor 12 compresses the input air stream 32 as described above.
  • the frequency of the electricity 50 produced by the generator is at least 1 ,000 Hz, and typically is from about 1 ,200 to about 1 ,600 Hz.
  • the turbine 16 may not operate at as high a temperature as the fuel cell can operate. Accordingly, it may be necessary to reduce the temperature of the spent fuel cell gas 56.
  • a slip stream 52 of the air compressed by the compressor 12 is combined with the fuel cell exhaust gas 40 upstream of the turbine 16. These two gas streams combined yield the turbine drive gas 48.
  • Spent turbine drive gas 58 is used for heating the compressed air stream 34 in the heating stage 20.
  • a slip stream 56 of the water 39 produced in the fuel cell is introduced into the heating stage 20 with the compressed air stream 34 to attemperate the compressed air.
  • a portion of the water vapor produced in the fuel cell is condensed before it is used to attemperate the compressed air. It is not necessary that the water used in the recuperator come from water produced in the fuel cell. Makeup water 61 from pump 63 can be used instead.
  • Spent turbine drive gas is discharged from the recuperator through line 72.
  • the alternating current electricity 50 from the generator 14 is rectified in the rectifier 22 to direct current electricity 64.
  • This direct current 64 is combined with the direct current 38 from the fuel cell, and inverted in the inverter 24 to produce alternating current power 66.
  • two inverters can be used, one for the direct current 38 from the fuel cell and the other for the direct current 64 from the rectifier 22.
  • the use of separate inverters is less preferred.
  • An advantage of the invention is that because of the relatively low pressure ratio used in the compressor 1 2, generally less than 4: 1 , intercooling between multiple compressor units, as required in some prior designs, is not needed.
  • Example A computer simulation of the system according to the present invention was run. Parameters for the process streams are presented in Table II.
